3.3.4 Level 4 Incremental Build

Objectives of this build level:

  • Evaluate motor identification with FAST estimators.
  • Evaluate the complete motor drive with FAST-based sensorless-FOC.
  • Evaluate the additional features, such as field weakening control, MTPA, and torque compensation.

In this build level, the outer speed loop is closed with the inner current loop for motor that the rotor angle is from FAST. The software flow for this build level is shown in Figure 3-15.
